You must have no other gods before me. (Ex. 20:3)
The call of God to Israel was to not only be free of the outward slavery of Egypt, but to have their hearts set free as well. 400 plus years of slavery didn’t just effect their physical and mental status. It enslaved their hearts as well.
The plagues on Egypt weren’t just for Pharaoh. They were for Israel. They needed Egypt out of their hearts just as much as they needed their bodies out of Egypt.
We often have too much of Egypt in us. We play with the gods of this age. We think we “play” with the God of all creation.
He didn’t save us to “play.” He saved us and called us to a new allegiance. No more Egypt.
